Power door locks on my s14

[bluezenkis14]

I have google searched this but no one seemed o have the exact problem I have
My main problem is that my drivers side door lock will lock with out a problem but when I try to unlock it with either the interior switch or keyless fob it seems to almost but not unlock and I am forced to use my key to unlock the door I saw somewhere that the actuator needs to be tightened? Can anyone give me more information on that? And also my passenger side door will not unlock with my key but will work electronically
Thanks
